Second Saltmarsh Sparrow Banded in New England Resighted in Florida

Pat and Doris Leary are avid birdwatchers and citizen scientists from Fernandina Beach, FL, who volunteer their time and substantial skills to survey coastal waterbirds in Northeast Florida, coastal Georgia and Florida’s Big Bend. This is the fourth of several blogs in which they share their experiences and sightings, as well as the challenges these increasingly imperiled birds face.

Erin searched with camera in hand and was able to photograph a briefly-sighted sparrow with a bright orange band. On a hunch, Erin later contacted Professor Brian Olsen, University of Maine, and was pleased to receive confirmation that the bird had been banded in either Maine or Connecticut as part of a multi-state population research study. The banding location is uncertain due to similarity of bands used on birds in both states.

 Borowske, University of Connecticut, during her February 2013 field work in Florida. Alyssa’s sparrow was traced to a breeding population in Maine.  These sightings are remarkable due to the high number of birds dispersed across thousands of acres of Florida marsh, the sparrows’ tendency to remain concealed, and the brief opportunity observers have to detect and record the tiny markers.  In Alyssa’s case she was fortunate to trap one banded bird amongst hundreds encountered during her field work here.

Northeast Florida’s coastal salt marshes support significant nesting populations of Seaside Sparrows and Marsh Wrens, but their numbers are substantially bolstered by an influx of migrant Seaside, Nelson’s, and Saltmarsh Sparrows each fall and winter.  Most originate from more northern Atlantic coast marshes, but some Nelson’s Sparrows breed in inland freshwater marshes hundreds of miles from the coast. In the winter, these species forage in the “drowned prairie” of coastal saltmarsh cordgrass and, despite their numbers, are seldom viewed by humans. On high tides, the birds concentrate in dense grass along marsh watercourses and on isolated marsh islands, but even there remain well concealed in vegetation. 

Florida's coastal saltmarsh habitatDue to early evidence of sea level rise and related tidal perturbations, concern is growing for the survival of these species whose lives are directly dependent on the thin margin of tidal marsh stretching along the coast. Consequently, more attention is being focused on the status and health of these birds to identify important habitats and environmental requirements. As data is gathered, it is becoming evident that our regional marshes support not only significant numbers of resident sparrows, but also substantial populations of migrant and wintering birds.

The next time you gaze across our expansive marshes be aware that, in addition to the colorful Roseate Spoonbills, Wood Storks, herons, egrets, and the myriad of smaller shorebirds, the rich ecosystem also supports an abundance of marsh-adapted sparrows and wrens concealed from view in the dense stands of cord grass that are the key element in the ecosystem’s fecundity. Stop, listen, and look carefully and you may catch a glimpse of these cryptically-colored birds that will give you a new awareness of the life within Florida’s coastal saltmarshes.


  1. You are wrong. I live in GA, and the forecast was not off by much. The issue is not snow preparedness, or southern drivers. The issue is foolhardy public officials and business managers who took a gamble.

    I am a biologist, so I pay CLOSE attention to National Weather Service. The forecast >48 hours out was for 1-4″ of “wintry mix” just south of metro Atlanta. I guess they figured that “it’s going south of us, we don’t have to worry”. HUH?!? The storm was off by maybe 2 degrees. So they got what was forecast a scant 30 miles away. Meaning the forecast was pretty damn good. The officials decided not to act, and THAT is what caused the cluster.

  2. I am so sorry… this was supposed to go into another window that was open, and I’m really not sure how this ended up on this page. Maybe the site owner can remove it for me?
